The expression “I will never forget you” gives consolation in farewells, hope in separation, and comfort in times of need. But depending on who expresses it, it can feel like an empty box or can have all the guarantees of authenticity. “Can a mother forget her nursing child? Can she feel no love for the child she has borne? But even if that were possible, I would not forget you!” (Isaiah 49:15 ). These words of the prophet are stamped with God’s own seal for his people. They inspire trust by showing that God’s bond with us is stronger than the strongest human bond: that between a mother and her child.
